Log Message:
1.0.10.5: dynamic-extent CONS

* Extend EMIT-FIXED-ALLOC to support stack-allocation.

* Appropriate DEFOPTIMIZER for CONS.

Note: it seems like it should be a simple matter to support stack
allocation of all primitive objects allocated using the :ALLOC-TRANS
framework.

   * optimization: UNION and NUNION are now O(N+M) for large
     inputs as long as the :TEST function is one of EQ, EQL, EQUAL, or
     EQUALP.
+  * enhancement: CONS can now stack-allocate on x86 and
+    x86-64. (Earlier LIST and LIST* supported stack-allocation, but
+    CONS did not:)
   * enhancement: DEFINE-MODIFY-MACRO lambda-list information is
     now more readable in environments like Slime which display it.
